| 摘 要： | 分别从生物处理法、化学氧化法、吸附法和电化学法等方面介绍了印染废水的处理方法和研究进展,介绍了放电等离子体技术、超临界水氧化技术、膜分离技术以及超声波技术等新兴的治污技术,分析了染料废水处理技术的研究状况。化学氧化技术使用广泛,一般常用于生物处理的前处理;吸附法的吸附效率较高,吸附过程不破坏染料的分子结构,染料可以回收利用;电化学技术不仅能去除重金属,而且能去除化学需氧量(COD)、生物需氧量(BOD)和总悬浮固体(TSS)浓度,对染料的脱色效果很好;超临界水氧化法使有毒有害的有机物完全转化,可以避免二次污染问题,氧化反应速率快,适用范围广;膜分离技术高效、节能,可实现废水的循环利用和有用物质回收;超声技术操作条件温和、降解速率快、可以单独使用或与其他水处理技术联合使用。
